Description

CROSS-REFERENCE TO RELATED APPLICATIONS

The present application is related to U.S. Pat. No. 8,365,218, entitled “Networked Television and Method Thereof,” U.S. Pat. No. 8,282,476, entitled “Multimedia-Based Video Game Distribution,” and U.S. patent application Ser. No. 11/166,908, entitled “Video Game Console Modular Card and Method Thereof,” now abandoned, which are assigned to the current assignee hereof, which were filed on even date herewith, and which are incorporated by reference in their entireties herein.

FIELD OF THE DISCLOSURE

The present application relates generally to processing audio data in a multimedia environment.

BACKGROUND

Many households make use of audio receivers to process audio information from various audio sources, such as televisions, broadcast transmissions, compact disk (CD) and digital versatile disk (DVD) players and the like. Conventional audio receivers, however, are implemented as separate or stand-alone devices that often require numerous wires and cables to provide desired connections between power sources, audio/video components (e.g., televisions or CD players), and one or more speakers. This multitude of cables and wires often results in an aesthetically unappealing jumble of wires around the audio receiver and the components to which it is connected. Moreover, because of their relative lack of integration with other components, it often is difficult to leverage the functionality of the audio receiver with the functionality of other multimedia components to provide an enhanced aural experience.

To illustrate, consumers typically must utilize a personal computer (PC) to receive and display video content streamed or otherwise provided via a computer network. However, PCs are designed to support a wide variety of functions, from Internet browsing and word processing to the processing of detailed scientific data. As such, PCs implement complex hardware architectures and sophisticated operating systems in order to be capable of supporting the widely divergent tasks expected of them. The complexity of PCs results in a user experience that is different from the traditional television experience in that they often require a substantial amount of time to “boot up” before they can be operated by a user, whereas conventional televisions typically are ready to provide video and audio content almost immediately. Moreover, with their multitude of exposed cables and constant fan noise, PCs often present an aesthetically unappealing solution for television viewing. Similarly, the set-top boxes typically required for receiving and processing digital cable transmissions often detract from the visual appeal of the television setting. Moreover, as opposed to PCs, conventional set-top boxes typically are of limited functionality in that they typically interface only with coaxial cable connections and provide functions directed to processing video and audio content of a cable television transmission.

In the illustrated example, some components of the television 100 can be connected via a first bus 232 while other components can be connected via a second bus 234. Further, the busses 232, 234 can be connected by a bus bridge 236.

The processor 202 can perform multimedia processing routines in accordance with an operating system (OS) 230 and facilitates the functions performed by the modular cards that are connected to the modular card receptacles 222-228 of the television 100 by routing information between the components or by handling various aspects of the functions performed by the modular cards. In a particular embodiment, in order to provide prompt, real-time interaction with a television user, e.g., by displaying video content promptly upon request, the OS 230 is a real-time OS having specific functionality that is configured to streamline the operations of the processor 230 and limit the delay between receiving a user request and providing the requested action.

For example, in one embodiment, the OS 230 is stored in the flash memory 206 when the television is powered down, and upon a user request to power up the television, e.g., via the user control buttons 104 or the remote control interface 106, at least a portion of the OS 230 is loaded into a cache of the processor 230 so that the video content of a video data source selected at power up is provided for display within at least ten seconds of receiving the request, or within five seconds or within two seconds of receiving the user request. Additionally, the streamlined OS 230 can allow the television 100 to display video content promptly upon receiving other types of user requests, such as a user request to change television channels or a user request to activate game play associated with video game data processed by the video game console modular card 146. As such, the television 100 can provide the traditional television experience in which changes in the video content displayed and/or the audio content output occur promptly in response to the user's input as one or more requests.

During operation, the various components of the television 100 communicate information via the busses 232 and 234 in order to perform various multimedia-related functions. For example, the communications processor 216 provides communications protocol-specific processing for data received via the network interface 118 and for data to be transmitted on a packet-based network via the network interface 118. Further, the communications processor 216 may implement one or more functions associated with, the Open Systems Interconnection (OSI) seven-layer model or the Telecommunications Protocol/Internet Protocol (TCP/IP) stack. During operation, incoming data that is processed by the communications processor 216 can be routed to one or more of the components of the television 100 as appropriate. The DMA controller 210 can control access to the RAM 204 and/or the ROM 206 by the components of the television 100. Moreover, the overlay graphics generator 214 can generates overlay graphics that overlay the display graphics that are output to the display 102 by the display controller 212.

In a particular embodiment, the modular cards 140-146 may communicate information with each other and with other components of the television, e.g., the processor 202 or the display controller 212, using the modular card receptacles 222-228 and the bus 234. For example, the wireless network interface modular card 142 or the network interface 118 may be used to receive/transmit multimedia data for the decoder modular card 140, receive/transmit audio data for the audio receiver modular card 144, or receive/transmit video game data and related information for the video game console modular card 146.

Referring to FIG. 3, an exemplary implementation of the multimedia decoder modular card 140 is illustrated in accordance with at least one embodiment of the present disclosure. In the example depicted, the multimedia decoder modular card 140 includes a modular card receptacle interface 302, an input buffer 304, a decryption module 305, a parser 306, a video decoder 308, a video output buffer 310, an audio decoder 312 and an audio output buffer 314. In a particular embodiment, the incoming buffer 304 and the output buffers 310 and 314 may be implemented together as a single buffer.

During operation, incoming multimedia data that is to be processed by the decoder modular card 140 is buffered in the incoming buffer 304. In at least one embodiment, the multimedia data is part of an MPEG data stream. Accordingly, the parser 306 parses the multimedia data to identify the relevant video and/or audio data to be processed. Then, the parser 306 provides the video data to the video decoder 308. The 308 decodes, or transcodes the video data and the resulting decoded/transcoded data can be stored in the outgoing video buffer 310 before being provided to the bus 234 (FIG. 2) for transmission to one or more components of the television 100. Similarly, the audio decoder 312 decodes or transcodes the audio data. Audio data is decoded/transcoded by the audio decoder 312 and the resulting decoded/transcoded audio data is buffered in the outgoing audio buffer 314 before being provided to the bus 234 for transmission to one or more other components of the television 100.

Alternately, in one embodiment, the received multimedia data includes unencoded multimedia data. In this instance, the video decoder 308 also may provide a video encoder to encode the video data to generate encoded video data (e.g., MPEG data) and the audio decoder 312 may include an audio encoder to encode the audio data to generate encoded audio data.

In at least one embodiment, the received multimedia data is encrypted or otherwise protected to prevent unauthorized access to the multimedia content. Accordingly, in at least one embodiment the integrated decoder modular card 140 further comprises a decryption module 305 to process the protected multimedia data to generate unprotected multimedia data using a decryption key 307 supplied by, for example, a provider of the protected multimedia data. In one embodiment, the decryption module 305 processes the protected multimedia data before it is provided to the parser 306. Alternately, the decryption module 305 could be implemented at the output of the parser 306 or as part of the decoders 308 and 312.

Referring to FIG. 4, an exemplary method 400 for processing multimedia data at a networked television is illustrated in accordance with at least one embodiment of the present disclosure. The method 400 includes receiving a multimedia data stream at the network interface 118 of the television 100 at block 402. At block 404, video data from the multimedia data stream is processed at a multimedia decoder of the television to generate video content. At block 406, audio data from the multimedia data stream is processed at the multimedia decoder of the television to generate audio content. The multimedia decoder may include a multimedia decoder that is integrated into a core processing component of the television (e.g., an MPEG decoder chip) or the multimedia decoder may include a multimedia decoder modular card 140, as illustrated in FIGS. 1-3. Further, in one embodiment, the audio data and video data are processed by separate components. To illustrate, the audio data can be processed by, for example, the audio receiver modular card 144 whereas the video data can be processed by an integrated multimedia decoder or the multimedia decoder modular card 140. At block 408, the video content is provided to the display 102 of the television 100 for viewing by a user. At block 410, the audio content is provided for output to one or more speakers. The speakers receiving the audio content may be speakers integrated with the television 100 or they may include, for example, speakers wired to the speaker outputs 152 (FIG. 1) or speakers wirelessly connected to the television 100 via the wireless network interface modular card 142 (FIG. 1).

Referring to FIG. 5, an exemplary method 500 for providing multimedia data to the television 100 is illustrated in accordance with at least one embodiment of the present disclosure. The method 500 includes providing a first data stream including multimedia data from a content provider to the television 100 via a packet-based network, such as, for example, an IP-compliant network at block 502. As noted above, the television 100, in one embodiment, includes a network interface 118 (FIG. 1) to a packet-based network to receive multimedia data and a multimedia decoder to process the multimedia data. As noted above, the content provider may seek to limit distribution of the multimedia content represented by the multimedia data. Accordingly, at block 504, the content provider can provide an indicator of a maximum number of televisions authorized to receive the multimedia content represented by the first data stream. In response to this indicator, the television 100 can provide data representative of the multimedia content to a number of networked devices at block 506, where the number of networked devices receiving the multimedia content is limited based on the indicator. Further, in one embodiment, the content provider may bill the user of the television 100 for services that include providing the first data stream.

Referring to FIGS. 6-8, an exemplary technique for redistributing multimedia data is illustrated in accordance with at least one embodiment of the present disclosure. As depicted by FIG. 6, a multimedia content provider 602 (e.g., an operation maintained by a cable television provider or telecommunications company) may be coupled to television 606 via a packet-based network 604, such as, for example, the Internet or a private network. As part of a broadcast, or in response to a user request, the content provider 602 provides encoded multimedia data 612 to the television 606 via the network 604. The encoded multimedia data 612 is received at the television 606 via a network interface (e.g., network interface 118, FIG. 1) connected to the network 604. The multimedia data 612 can be processed by a multimedia decoder of the television 606 (e.g., multimedia decoder modular card 140, FIG. 1) to generate processed multimedia data 614. Various operations performed on the multimedia data 612 by the television 606 to generate the processed multimedia data 614 may include decoding or transcoding the multimedia data 612, decrypting the multimedia data 612, and the like.

The resulting processed multimedia data 614 can be provided to one or more networked devices for further processing and/or display. In the example illustrated by FIG. 6, the processed multimedia data 614 is transmitted to another television 608 via the network 604. The television 608 may further process the multimedia data 614 for display or for storage. In the example illustrated by FIG. 7, the processed multimedia data 614 may be communicated wirelessly between the television 606 and the television 608 using wireless transceivers 702 and 704, respectively. The wireless transceivers 702 and 704 may be implemented as, for example, the wireless network interface modular card 142 (FIG. 1).

FIG. 8 illustrates an exemplary method 800 for redistributing multimedia content as described with respect to FIGS. 6 and 7. The method 800 includes receiving a first multimedia data stream at a first network interface of a television at block 802, wherein the first network interface is coupled to a packet-based network. The first multimedia data stream may be provided as a scheduled broadcast or may be provided by a content provider in response to a user request for the first multimedia data stream. At block 804, the first multimedia data stream is processed at a multimedia decoder of the television to generate a second multimedia data stream. The multimedia decoder can include, for example, an integrated multimedia decoder or the multimedia decoder modular card 140 (FIG. 1). The processing performed on the first multimedia data stream can include, for example, decoding the first multimedia data stream or transcoding the first multimedia data stream. Moreover, in one embodiment, the first multimedia data stream may include protected multimedia data. Accordingly, the processing performed on the first multimedia data stream further may include decrypting the first multimedia data stream including the protected multimedia data. At block 806, the second multimedia data stream is provided to a networked device via a second network interface of the television. The second multimedia data stream may be provided via the same packet-based network used to receive the first multimedia data stream. In this case, the second network interface and the first network interface may be the same network interface. Alternately, the second multimedia data stream may be provided via another packet-based network (e.g., a wireless network) and therefore may be a different network interface than the first network interface.

The exemplary techniques illustrated in FIGS. 6-8 allow a single television to act as the distribution point for multimedia content received from a content provider. To illustrate, because the television 100, in one embodiment, decodes and/or decrypts the encoded multimedia data 612 to generate unencoded and/or decrypted multimedia data 614, the networked devices receiving the multimedia data 614 (e.g., television 608) do not need to utilize a decoder and/or decryption module to process the multimedia data for display as video and/or audio content. As a result, the decoding/decryption components of the networked devices receiving the multimedia data 614 may be disabled, thereby reducing the power consumption of the networked devices. Moreover, the networked devices may be supplied without decoding/decryption components, thereby reducing their complexity and cost.

Referring to FIGS. 9 and 10, an exemplary implementation of the audio receiver modular card 144 is illustrated in accordance with at least one embodiment of the present disclosure. As illustrated, the audio receiver modular card 144, in one embodiment, includes a modular card receptacle interface 902, a buffer 904, one or more digital signal processors (DSPs) 906, a digital-to-analog converter (DAC) 908, an RF interface 910, an analog-to-digital converter (ADC) 912, a display control module 914, the audio input 150 and one or more speaker outputs 922-930.

In operation, audio data to be processed can be received from other components of the television via the modular card receptacle interface 902 or from an external audio source via the audio input 150 or via an RF transmission received at the RF interface 910 and converted to digital data by the ADC 912. The received audio data can be buffered in the buffer 904 until accessed by the DSP 906 for processing. Processing operations performed by the DSP 906 can include, for example, decoding (e.g., decoding from an MPEG or MP3 format), decryption, filtering, stereo enhancement, equalization and the like. For example, in one embodiment the DSP 906 performs surround sound processing of the audio data consistent with one or more surround sound standards, such as Dolby Digital 5.1, Dolby Digital Theater System (DTS) Surround, THX Surround EX™, and the like.

The resulting processed audio data may be provided to one or more other components of the television via the modular card receptacle interface 902. For example, the processed audio data may be provided for output to one or more wired speakers via the speaker outputs 922-930 after digital-to-analog conversion by the DAC 908. In the illustrated example, the speaker output 922 connects to a right rear (RR) speaker, the speaker output 924 connects to a right front (RF) speaker, the speaker output 926 connects to a center speaker, the speaker output 928 connects to a left front (LF) speaker and the speaker output 930 connects to a left rear (LR) speaker. Alternately, as illustrated with reference to FIG. 10, the processed audio data (illustrated as audio data 1001) can be provided from the audio receiver modular card 144 to the wireless network interface modular card 142 for transmission to one or more wireless speakers 1002-1008.

In at least one embodiment, the display control module 914 provides display content representing information about the audio receiver modular card 144 for display on the display 102 (FIG. 1). For example, the display control module 914 may provide graphical data representing equalization settings, where the graphical content of the graphical data is laid over video content from another source on the display 102. Other information for display can include, for example, volume settings, speaker setup, artist and track information, and the like. Moreover, in one embodiment, the operation of the audio receiver card module 144 is responsive to user commands (e.g., remote control commands). For example, after displaying the current equalization settings on the display 102, remote control commands from a user representing a desired change in equalization settings can be received by the display control module 914. In response, the display control module 914 can send a signal to the DSP 906 to change the equalization settings as well as provide updated equalization settings graphical display information for display by the display 102 so that the user can visual confirm that the requested changes are made. Other operations affected by user input can include, for example, volume settings, channel selection, track selection, speaker setup, surround sound settings, and the like.

Referring to FIG. 11, an exemplary method 1100 for providing audio data for processing at a networked television is illustrated in accordance with at least one embodiment of the present disclosure. The method 1100 includes providing an audio data stream to the television via a packet-based network at block 1102. In one embodiment, the television comprises an exterior interface panel including a plurality of interface connections, a network interface to the packet based network to receive the multimedia data, and an audio receiver modular card (e.g., audio receiver modular card 144, FIG. 1) to process the audio data stream. In certain instances, a content provider may attempt to protect the audio data stream by encrypting the audio data. In such instances, the audio receiver modular card may have access to a decryption key provided by the content provider, at block 1104, or otherwise made available to the audio receiver modular card. The audio receiver modular card thus may use this decryption key to decrypt or otherwise decode the protected audio data. At block 1106, a user of the television is billed for services including providing the audio data stream to the television. For example, the user may have subscribed to a service and may receive a monthly bill.

Referring to FIG. 12, an exemplary method 1200 for processing audio data using the audio receiver modular card 142 is illustrated in accordance with at least one embodiment of the present disclosure. The method 1200 includes receiving first audio data at an audio receiver modular card of a television via a first network interface of the television (e.g., network interface 118 of television 100, FIG. 1) at block 1202. At block 1204, the first audio data is processed at the audio receiver modular card to generate second audio data. Processing operations performed by the audio receiver modular card may include, for example, decoding, filtering, formatting, and the like. At block 1206, the second audio data is provided for output to one or more speakers. In one embodiment, the second audio data is provided to one or more speakers via one or more speaker outputs of the audio receiver modular card.

In operation, video game data is provided to the television 100 via a network or by an external video game data source, such as a DVD player. The video game data is forwarded to the game console modular card 146 via the modular card receptacle interface 1302. The video game data may be stored in flash memory 1304, RAM 1308 and/or the hard disk 1312. The video game tuner 1316 manages the storage of video game data supplied to the television via one or more transmission channels.

The processor 1306 executes instructions represented by the video game data in response to user game controller signals received via the game controller interfaces 156. As noted above, the game controller interfaces 156 may include interfaces to wired game controllers or may include wireless interfaces to wireless game controllers. Data representing the video content of the game play is provided to the graphics engine 1314 whereupon the data is rendered into display data for output to the display 102 (FIG. 1) of the television. Data representing the audio content is processed by the processor 1306 or by an audio decoder (not shown) of the modular card 146. Alternately, the audio data is provided to the audio receiver card 144 or to the multimedia decoder card 140 for processing. The resulting audio content is output to one or more speakers associated with the television (e.g., integrated speakers or speakers connected via the audio receiver modular card 144, FIG. 1). The data representative of the video/audio content can be provided to a core component of the television 100 (e.g., the processor 202 or a dedicated television graphics engine) via the modular card receptacle interface 1302 for rendering into display data and output audio content.

In some instances, the game play represented by the video game data may be multiplayer game play that occurs among multiple players in separate locations. Accordingly, in at least one embodiment, the processor 1306 provides game play information for transmission by other game consoles involved in the same game play. To illustrate, the game play information is provided to the other components of the television 100 via the modular card receptacle interface 1302, whereby the game play information may be communicated to other networked game consoles via the network interface 118 (FIG. 1) or wirelessly communicated to other wireless game consoles via the wireless network interface modular card 142 (FIG. 1).

Referring to FIG. 14, an exemplary method 1400 for processing video game data at a video game console modular card of a television is illustrated in accordance with at least one embodiment of the present disclosure. The method 1400 includes receiving video game data at the television via a network interface to a packet-based network at block 1402. In one embodiment, the video game data is received as part of a multimedia data stream transmitted by a multimedia content provider via the packet-based network. For example, the video game data could be represented by one or more transmission channels of the multimedia data stream. At block 1404, at least a portion of the video game data is provided to the game console modular card (e.g., the game console modular card 146) via a first modular card receptacle of the television. At block 1406, the video game data is processed to provide game play content for display by the television, wherein the game play content is based on user control signals received via one or more game controller interfaces of the game console modular card. At block 1408, video game data associated with the game play is rendered at a graphics engine of the game console modular card to generate rendered display data, and, at block 1410, the rendered display data is provided for display via the first modular card receptacle. At block 1412, game play information is communicated with one or more networked devices (e.g., other networked televisions having game console modular cards) via the first network interface or via a second network interface, such as a wireless network interface modular card.

Referring to FIGS. 15-18, exemplary techniques for providing video game data via one or more transmission channels are illustrated in accordance with at least one embodiment of the present disclosure. FIG. 15 illustrates an exemplary video game distribution system 1500 including a video game provider 1502 and a networked device 1504 connected via a network 1506. The networked device 1504 may include any of a variety of devices capable of receiving and processing multimedia transmissions comprising a plurality of transmission channels (such as, for example, a digital cable transmission or a satellite television transmission). For ease of illustration, the networked device 1504 is discussed in the context of a networked television as described in detail above.

In the illustrated embodiment, the video game provider 1502 includes video game data storage 1510 for storing video game data associated with one or more video games, a list generator 1512, a multimedia stream generator 1514, and an authentication module 1516.

In operation, the multimedia stream generator 1514 generates one or more multimedia data streams 1520 for transmission to the networked device 1504. In addition to transmission channels having conventional video and/or audio data representative of television programs or radio programs, such as video channels 1521 and 1522, one or more transmission channels of the multimedia data stream 1520 can include video game data, such as game channels 1523-1525. Accordingly, to download the video game data associated with a particular video game, the networked device 1504 may select the game channel of the multimedia data stream 1520 associated with a desired video game and may store video game data transmitted via the selected channel.

To illustrate, a user of the networked device 1504 may provide a remote control command or other user input that causes the networked device to “tune” to a transmission channel selected by the user. Once “tuned” to this channel, the networked device 1504 may provide a request for the associated video game data from the video game provider 1502. The authentication module 1516 authenticates an identifier associated with the user request to determine whether the user is authorized to access the video game data. If so authorized, the multimedia stream generator 1514 obtains the requested video game data from the video game data storage 1510 and inserts the requested video game data into the appropriate game channel of the multimedia data stream 1520. The authentication module 1516 further may store the request for video game data for billing purposes associated with providing the requested video game data.

Alternately, the video game data associated with one or more video games may be inserted by the multimedia stream generator 1514 in a repeating manner. In this instance, once the networked device 1504 is “tuned” to the selected game channel, the networked device 1504 may delay storing the video game data in the selected game channel until the starting byte of the video game data is retransmitted in the next iteration. Rather than waiting for the starting byte of the video game data, the networked device 1504 instead can identify an entry point where the networked device 1504 began storing video game data transmitted in the selected game channel and can cease storing video game data when the identified entry point is encountered again during the next transmit iteration of the video game data. For example, if the networked device 1504 tunes to the selected channel and starts recording the video game data at byte 1000, the networked device 1504 would continue to record the video game data through the end byte of the present iteration until byte 999 of the next iteration is encountered. Thus, the networked device 1504 can store the entire video game data without delaying until the start of the next iteration of the transmission of the video game data in the selected transmission channel.

The association of video games and their corresponding transmission channels may be provided to a user in any of a variety of ways. For example, a printed publication could be provided that indicates which transmission channels are used to carry the video game data of certain video games. However, the use of a printed publication typically results in a static assignment of channels and may cause inconvenience on the part of the user if the printed publication is misplaced or otherwise unavailable. Accordingly, in at least one embodiment, the list generator 1512 generates one or more lists for display as video content, where the lists, when displayed, provide an indication of available video games and identifiers (e.g., channel numbers) of their corresponding transmission channels. An exemplary display of a list is discussed below with reference to FIG. 16. The lists of available video games may be organized by any of a variety of characteristics, such as rankings, genres, costs, system requirements, and the like. To illustrate, the list generator 1512 can generate, for example, a list of the top five video game rentals, a list of the top ten best selling video games, a list of newly introduced video games, a list of action/adventure video games, a list of role-playing video games, a list of video games suitable for children, and other lists.

Multimedia data representative of the one or more generated lists can be provided to the networked device 1504 as one or more list channels, such as list channels 1526 and 1527, of the multimedia data stream 1520. Accordingly, when the networked device 1504 is “tuned” to a list channel, the network device 1504 may provide the video content representative of the list associated with the selected list channel for display at the networked device. The user, upon viewing the video content representative of the list, may ascertain the transmission channel carrying data for the video game in which the user is interested. The user then can direct the networked device 1504 to “tune” to the identified transmission channel (using, for example, remote control commands) so that the video game data can be obtained from the identified transmission channel and stored (e.g., at the hard disk 1312 of the video game console modular card 146, FIG. 13) for subsequent use.

Referring to FIG. 16, an exemplary display of a list of video games at a networked device (e.g., the television 100, FIG. 1) is illustrated in accordance with at least one embodiment of the present disclosure. In the depicted example, the displayed list 1600 provides a listing of five available video games (video games A, B, C, D and E) identified as being the top five in rental frequency. Each video game listed also includes a visual indicator of the transmission channel that carries the video game data representing the video game. For example, the visual indicator may include “select channel” icons 1602-1610 corresponding to video games A-E, respectively, where the icons 1602-1610 provide a visual representation of the corresponding transmission channels (e.g., channels 101-105). The displayed list 1600 further may include screen shots 1612-1620 for one or more of the listed video games, as well as written descriptions, critic reviews or ratings of the listed video games (not shown).

Referring to FIG. 17, an exemplary method 1700 for providing video game data as one or more transmission channels of a multimedia data stream is illustrated in accordance with at least one embodiment of the present disclosure. At block 1702, a multimedia data stream is provided for reception by a display device, where the multimedia data stream includes a first channel having video content representing a first list of available video games and their corresponding channel identifiers and a second channel having video game data associated with a first video game of the first list and where the second channel is associated with a first channel identifier corresponding to the first video game. The multimedia data stream also can include other channels associated with other video games. The multimedia data stream can be provided as, for example, a digital cable television transmission or a satellite television transmission, a multimedia data stream transmitted over a packet-switched network. In at least one embodiment, the display device is a networked device, such as a networked television as discussed above.

To discourage unauthorized access, the video game data can be encrypted, such as at the video game content provider, prior to providing the multimedia data stream or prior to inserting the video game data into the multimedia data stream. Accordingly, a decryption key that is used to decrypt the encrypted video game data may be provided by the video game content provider or otherwise made available to the networked device. In one embodiment, the identification of the networked device is verified prior to providing or making the decryption key available. This verification process may include verifying that the particular display device and/or a particular user are authorized to use the video game data.

In one embodiment, the video game data associated with the first video game is provided in a continuous loop as the second transmission channel. Alternately, the video game data associated with the first video game is provided by a video game content provider in response to a user request for the video game data from the networked device. The user request may be initiated by a user remote control command directing the networked device to tune to the transmission channel identified by the first channel identifier.

As noted above, the multimedia data stream may represent the transmission of multimedia content in accordance with a service agreement or arrangement between a user and a content provider. Accordingly, at block 1704 the user's access of the video game data from the second channel is noted at the content provider and a charge is included in a billing statement sent to the user for the service that includes providing the multimedia data stream.

Referring to FIG. 18, an exemplary method 1800 for obtaining video game data from one or more channels of a multimedia data stream is illustrated in accordance with at least one embodiment of the present disclosure. The method 1800 includes receiving a multimedia data stream at a system including a display device at block 1802. The multimedia data stream includes a first channel having video content representing a first list of available video games and their corresponding channel identifiers and a second channel having video game data associated with a first video game of the first list. The second channel is associated with a first channel identifier corresponding to the first video game. In one embodiment, the system includes a networked television (e.g., television 100, FIG. 1) having a game console modular card (e.g., game console modular card 146, FIG. 1) to process the received data. In one embodiment, the storage of video game data at a hard disk 1312 (FIG. 13) of the game console modular card 146 is handled by the video game tuner 1316.

At block 1804, the video content representing the first list of games is provided for display at the display device. In the event that the system includes a networked television as described above, the networked television may include a decoder, such as an integrated decoder or a decoder modular card 140 (FIG. 1) to generate display data representative of the video content of the first channel for viewing by the user. At block 1806, user input indicating a selection of the first channel identifier associated with the first video game of the first list is received in response to display of the video content. The user input may include, for example, a request to “tune” the system to the transmission channel associated with the first channel identifier, where the request may be a remote control command or input received via, for example, a channel change button.

At block 1808, the video game data associated with the first video game from the second channel is obtained for storage at the system in response to receiving the user input. As noted above, the video game data may be provided in a single transmission at a predetermined time or in a continuous loop or the video game data can be added to the multimedia data stream in response to a request by the user. In the event that the data is provided in a continuous loop, obtaining the video game data can include identifying a start position within a present loop of the video game data and continuing to store the video game data until a corresponding position to the start position is encountered for the next loop of the video game data. In the event that the video game data is encrypted, at block 1810, a decryption key can be received at the system in response to a verification of an identification of the system. At block 1812, the video game data can be decrypted using the decryption key. In the event that the system includes the networked television 100, the obtained video game data can be stored at the hard disk 1312 (FIG. 13) of the video game console modular card 146 of the television 100 for subsequent processing to provide game play to a user.
